Real time continuous Prop balancing

Did anyone use BalanceMasters device bolted on their ultralight prop?

These devices apparently balance the prop continuously as you fly.
Similar devices are used on truck wheels - see www.BalanceMasters.com
and www.centramatic.com


Which raises the question if the prop is correctly balanced in the first
place why would you need dynamic balancing in an aircraft? It would seem
to me G forces would throw it off anyway.

Maybe because balance changes with prop speed? I don't know anything
about the specific unit in question, but, in theory, an onboard real
time continuous balancer seems useful - at least for the fixed pitch
crowd.

I recently spent $250 for prop balance and it did not work. It was
still about .2 ips out. A factory prop is usually fairly close and all
it needs is a few grams to correct it.
Such a continuous balance device would also take care of imbalance as
the prop gets nicks and scratches. It might even help in flight with
accidental prop damage. These are some of the good reasons...

Not to mention this could well be a solution in search of a problem.

When it comes to RELIABLE flying...
